Abstract
An exemplary switch having a housing that includes one contact bolt per phase. Each contact bolt moving along a longitudinal axis. In a first position on the axis, the contact bolt connects two active parts to one another. In a second position on the axis, the contact bolt is connected to a fixed earthing contact piece. A drive motor actuates the contact bolts via a drive spindle. The lines of movement of each contact bolt all phases lie in a common plane, wherein each contact bolt is driven by one insulating spindle, which is aligned with the line of movement. The drive spindle lies in the plane of the lines of movement and runs perpendicular to the insulating spindles and is coupled to each insulating spindle via a respective deflecting gear mechanism. The deflecting gear mechanism for the drive of the contact bolts is accommodated in the earthing contact pieces.
